1J ECIFICATION forming part of Letters Patent No. 316,665, dated August3, 1886.

Application filed April 6, 1856. Serial No. 197,955. (No mo el.)

To all whom, it 17mg concern.-

Be it known that I, ANDREW J. LIND UIsT, of Bertrand, in the county ofPhelps and State of Nebraska, have invented a new and Improved Windmill,of which the following is a full, clear, and exact description.

My invention relates to the construction of a windmill designed moreespecially for use in the pumping of water, but applicable to many otheruses in the mechanic arts; and the invention consists of other detailsof construction and combinations of parts, to be hereinafter more fullydescribed, and specifically pointed out in the claim.

Reference is to be had to the accompanying drawings,forming a part ofthis specification,in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is a perspective view of my improved windmill. the revolvingstandard and connections, and

' Fig. 3 is a sectional plan view taken just above the platform.

In constructing the mill forming the sub- 2 5 ject-matter of thisapplication, and illustrated in the drawings above referred to, Iprovide a main frame, A, which serves as a support for the centralrevolving standard or tower, B, said tower B being, as usual, mounted ina step, 0, and passing up through an aperture formed in the center ofthe platform a, carried by the frame A. Just above the level of theplatform a the standard or tower B is provided with a drum, 1), that isfaced with a metallic collar, 0, that bears upon anti-friction wheels (1(I, carried bya ring, 6, that is arranged about the drum 1), the wheels6 bearing upon a hoop, F, arranged as best shown in Fig. 2.

As usual, the standard or towerB is formed of two vertical posts thatare firmly united at thetop and bottom, and spaced so as to leave arecess within which the pitman D works. Upon one side of the verticalposts constituting the revolving standard or tower there are securedboxes 9 g, which serve as the bearings for a crank shaft, E, upon whichthe wheel F is mounted, and from this construction it will be seen thatthe axis of the wheel is at one side of the axis of the revolving standard or tower B. The inner end of the vane Fig. 2 is a plan view of- G isprovided with a metallic strap, h, through which there is passed astaple, k, that is firmly secured to one of the posts of the revolvingstandard, the construction being such that the vane is free to swingupon its connection with the standard. Above the pivotal connection ofthe vane the standard B is provided with two projecting arms, one ofwhich, H, extends in a line parallel with the wheel, while the other, I,extends at right angles to the wheel or directly to the rear. To the armI there are connected two chains, Z and m, which branch from a singlechain, n, that is secured to the beam 0 of the vane G, the adjustment ofthe vane being controlled by the position of the chains Z m upon the armI, said arm carrying links 7' 1", formed with hook-s r, to which thechains are secured, or being provided with any other form of adjustableholding device that will suit the requirements of the case.

The arm H carries a sheave, 2', over which there is passed a chain, p,one end of whichis secured to the beam of the vane while the other isfixed to one of the vertical posts of the revolving standard or tower,the length of the chain being adjusted so that the'vane cannot swing outbeyond the position shown best in Fig. 2that is, cannot swing so as toextend at right angles to the wheel. To the chain 1) there is secured achain, 1), as shown in Fig. 1, said'chain passing down through an eye,q, carried by the standard, to a cleat, q, where it is secured,thearrangement being such that by pulling down on the chain 19 the vane Gwill be drawn up against the spring-arm N, carried by the arm H, thisdrawing up of the vane being done when it is desired to throw thewindmill out of action.

In practice I prefer to mount the wheel about three inches to the leftof the axis of the revolving tower, so that when the wind becomes toostrong the wheel will turn out of the wind. The chain Z should beadjusted upon the arm I so that the vane will project out about as shownin Fig.- 1--that is, if the wheel overspeeds before it turns out of thewind, the chain is moved down the arm I toward the tower B, and a linkor two given out to increase the length of the chain. If it is desiredto have the mill run fast, the chain at is shortened, and when it isdesired that the mill should run slower-that is, be more easily turnedout of the wind-the chain on is lengthened and its supporting-link moveddown to ward the revolving tower D, and when it is desired to throw themill out of use the vane G is carried up against the spring-arm N.

angles to each other, the pulley i on the arm H. and the hooks r r onthe arm I, of the wheel, the crank-shaft on which the wheel is mounted,the staple k on the tower below the arm I, the vane G, having a beam, 0,provided with the strap h, engaging the said staple, the chain a,connected at its lower end to the vane, the chains 1 m, engaging thehooks r and connected to chain a, the rope p, secured to the vane,passed over the pulley t, and secured to the tower or shaft, and theoperating-rope 19, secured to the rope 19, substantially as set forth.
